摘要
建立了为辅助设计强流负离子束引出、加速系统进行数值模拟研究的数学模型 ,简述了数值计算方法。对系统的电、磁场位形进行优化 ,并给出了 30 0keV、5电极负离子束系统的初步优化结果。
A mathematical model for numerically simulating high current negative ion beam extraction and acceleration system has been established in order to assistantly design.The related computation method is described briefly.The electric and magnetic field conformation in the system is optimized and the initial optimized results of the 300 keV\,5 electrodes negative ion beam system is given as well.
